2022-02-22

　　On June 22, a group of 13 leaders, including Inspector Yan Wanda from the Provincial Federation of Trade Unions, Chairman and Standing Committee Member of the Municipal Federation of Trade Unions Zhao Jing, Secretary of Binhai New Area Yang Lin, Deputy Director Yang Xu from the Provincial Federation's Research Office, Deputy Minister Yang Ren from the Provincial Federation's Department of Economics and Technology, Deputy Editor-in-Chief Yang Lihua from the Contemporary Workers Magazine, Vice Chairman Zuo Liya from the Municipal Federation of Trade Unions, Member of the Standing Committee and Head of the Economic Auditing Committee He Yougang from the Municipal Federation of Trade Unions, Section Chief Guan Feng from the Provincial Federation's Department of Economics and Technology, and Chairman Kumamoto from Binhai New Area, visited Han Hua Electric Fitting Company for the provincial top ten rationalization suggestions commendation and high-skilled talent research.
　　The commendation mainly focused on the "Provincial Top Ten Rationalization Proposals and Excellent Proposals" selection activity organized by the Provincial Federation of Trade Unions in 2015. Han Hua Electric Fitting Union's entry, "Suggestions on the Rationalization of Electroplating," won first place in Liaoning Province. The Provincial Federation of Trade Unions, the Municipal Federation of Trade Unions, and the Binhai New Area Trade Union each awarded a prize of 10,000 yuan. Inspector Yan Wanda, Chairman and Standing Committee Member Zhao Jing, and Secretary Yang Lin presented the award on-site and commended and encouraged the Han Hua Electric Fitting Company's trade union work.
　　In addition, General Manager Ma and the head of the Human Resources department of Han Hua Electric Fitting Company held a research meeting on high-skilled talent with the provincial and municipal federations of trade unions.

What are the structural hotspots of a starter armature?

The starter armature moves the entire armature through the magnetic force of the magnetic poles, causing the drive gear to mesh with the flywheel gear ring. The armature of the starter is offset from the magnetic pole by a certain distance under the action of the reset spring, and the commutator is relatively long. The starter housing is equipped with an electromagnetic switch. Its magnetizing coil is controlled by the starter switch S. The movable contact is the contact bridge. The upper end of the contact bridge is longer and the lower end is shorter, so the starter circuit can be connected in two stages. The starter has three magnetic field windings. Among them, the main magnetic field winding with fewer turns is made of flat copper bars, and the other two fine wire windings are the series auxiliary magnetic field winding and the parallel auxiliary magnetic field winding (also called the holding coil). The starter one-way clutch generally uses a friction plate clutch. The working process of the starter armature is divided into two stages. The series auxiliary excitation winding mainly works in the first stage, and in the second stage it is almost short-circuited due to being in parallel with the main excitation winding; the parallel auxiliary excitation winding works in both stages, which not only increases the magnetic force attracting the armature, but also limits the no-load speed. (1) Engagement When the starter switch S is turned on, the electromagnet generates suction to attract the contact bridge. However, because the pawl rests against the blank, the contact bridge can only close at the upper end, and the series and parallel auxiliary magnetic field winding circuits are turned on. The current circuit is:

Starter armature: What is an armature?

The starter armature manufacturer states that motors play a key and crucial role in the process of achieving mutual conversion between mechanical energy and electrical energy. For generators, it is the component that generates electromotive force, such as the rotor in a DC generator and the stator in an AC generator; for motors, it is a component that generates electromagnetic force, such as the rotor in a DC motor. The starter armature manufacturer states that the armature is the relative motion of the coil relative to the magnetic field of the coil-carrying component in the motor. In a generator, an induced electromotive force is generated in a forced rotating coil to generate electricity. In a motor, the energized coil is subjected to Ampere force in the magnetic field, causing it to rotate in the magnetic field. In the mid-19th century, the term "armature" was early used for inductors, i.e., holders of magnets. Part of an alternator or related equipment can be represented by any mechanical or electrical aspect. Although these two sets of terms are clearly separated, they are often used interchangeably, or a combination of mechanical and electrical terms is included. This can cause confusion when using composite motors such as brushless alternators, or when talking to people accustomed to using different configurations of motors. The starter armature manufacturer states that in most generators, the field magnet is rotating and is part of the rotor, while the armature is stationary.

Starter armature: armature knowledge points

The armature manufacturer states that the armature plays a key and crucial role in the process of converting mechanical energy and electrical energy into each other. For generators, it is the component that generates electromotive force, such as the rotor in a DC generator and the stator in an AC generator; for motors, it is a component that generates electromagnetic force, such as the rotor in a DC motor. The armature is the part of a motor that has coils, and the coils move relative to the magnetic field. In a generator, an induced electromotive force is generated in the forced rotating coil to generate electricity. In a motor, the energized coil is subjected to the Ampere force in the magnetic field, causing it to rotate in the magnetic field. The armature manufacturer states that in most generators, the field magnet is rotating and is part of the rotor, while the armature is stationary and is part of the stator. Motors and generators can be composed of a stationary armature and a rotating magnetic field or a rotating armature and a stationary magnetic field. The pole shoes and moving iron parts of permanent magnets or electromagnets and solenoids (especially when the latter are used as switches or relays) can also be called armatures. The armature manufacturer states that armatures are divided into two categories: DC armature windings and AC armature windings. They are used in DC motors and AC motors respectively. Including the armature core and the armature winding, the armature winding is the circuit part of the DC motor,
